Costeño Beach Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s take a long look at what’s shaping up for Costeño Beach. This is a beginner-friendly, consistent spot that’s exposed to the swell, and it’s a consistent performer, so even when it’s not firing, there’s usually something to work with.

Right now, we’re heading into a bit of a slow patch. The water temp is sitting at 82°, which is spot on for this time of year – no surprises there.

The first real action kicks off Tuesday morning, the 11th. We’ve got a 7ft northeast swell rolling in with a 9-second period, packing a moderate energy of 568. The wind is a light cross-onshore, so it’s not glassy, but it’s rideable. That afternoon, the swell bumps up to 8ft, still from the northeast, and the energy climbs to 796. The wind stiffens a touch and stays cross-onshore, so it’s a bit choppy, but there’s push.

Wednesday the 12th sees the swell drop to 5ft in the morning, period shortening to 8 seconds, energy down to 316. Still cross-onshore. By afternoon, a shift to a light onshore wind from the north-northeast brings in 5ft waves. It’s not great, but a beginner could have a splash.

Thursday the 13th is similar – 5ft all day, same northeast direction, period 8 seconds. Winds are light, cross-onshore in the morning, turning onshore in the afternoon. Energy sits around 235 to 253. Nothing to write home about.

Friday the 14th picks up a bit. Morning sees 7ft from the northeast, period 9 seconds, energy 645. The wind is a gentle cross-onshore, so it’s a bit lumpy. That afternoon, the swell hits 8ft, energy 816, with a light onshore wind. It’s surfable, but not clean.

Now, Saturday the 15th is the standout of the first week. The swell jumps to 8ft, period 10 seconds, and the energy is seriously pumping – 1150 in the morning, 1064 in the afternoon. This is a strong, powerful swell. The wind stays cross-onshore, light in the afternoon, so it’s not perfect, but for a consistent beach break, 8ft of northeast swell with that much energy is a solid session. Keep in mind, at this size, it’s getting into the intermediate zone, maybe a bit much for true beginners.

Sunday the 16th drops off fast. Morning is 6ft, but the wind is a gentle cross-onshore and the conditions are rated poor. Afternoon is 7ft but with a short 7-second period. Energy drops to 459 and 412. Not worth the paddle.

Monday the 17th is small – 4ft in the morning, but the afternoon brings a surprise. A light offshore wind from the south at 3 mph, with 5ft northeast swell, and the comment says “expect good surf conditions.” That’s the cleanest window we’ve seen, with a 226 energy. It’s small, but glassy offshore conditions make it fun for a longboard or a log.

Tuesday the 18th is dead flat in the morning – glassy, 4ft, 8 seconds, energy 171. Afternoon is 3ft from the north-northeast. Not happening.

From Wednesday the 19th through to the end of the 16-day window, it’s a long stretch of marginal surf. Waves hover between 4ft and 6ft, mostly with short periods of 7 to 8 seconds, and light cross-onshore or onshore winds. There are a few glassy windows on the 20th, 21st, and 22nd, but the swell is small and weak – energy mostly under 300. The best of this second week is Saturday the 22nd, with 5ft and glassy conditions in the afternoon, energy 300, but it’s still a weak, short-period swell.

Overall, the real highlight is Saturday the 15th – that 8ft, 10-second northeast groundswell with strong energy is the biggest, most powerful swell of the stretch. It’s not perfect with the cross-onshore wind, but it’s the most juice you’ll see. The Monday the 17th afternoon window is the cleanest, but it’s small. The rest is a long, drawn-out run of average to poor conditions. For a beginner spot, it’s not great, but for a keen surfer, the 15th is worth a look.

Rusty, signing off.
